Question on Ultrasound Sizes

Hey ladies, well as you know I found out I am having a little boy.. My question is regarding his size and how accurate the ultrasound could actually be..
My first ultrasound was done at 8 1/2 weeks and that gave me a due date of August 8th..
This most recent ultrasound I had I was around 21w4ds, and he was measuring a full week ahead  and was said to be around 1lb and 2ozs.. with the due date of August 1st.. is this an accurate measurement.. my dr said he probably wouldn't change it.. I'm just curious as to why and if anyone has been in the same situation.. Thanks again

I would stick to the original due date...babies grow at diffrent rates and u/s done later in pregnancy aren't as accurate as when they are done in the begining.
I am measuring 2 weeks further along and I am going by my first u/s dating witch is 1 week ahead of my LMP! I have 2 kids already and have never made it to my due date.....my last baby was 2 weeks early and 7 and 1/2 lbs!! I cant amagine having went the full 40 weeks, lol!!
Besides...the same as babies grow at diffrent rates, they also come into this world when they want to too!! Due dates are just an guess as to when your baby will be born...it can happen anytime:)
Hope this helps:)

my EDD according to my first scan is 25th August but im not sure thats right as have no LMP to go by.

My doc thinks im measuring 2-3 weeks in advance so dated me at around 22.5 weeks but my latest scan didnt change my EDD either.

Strange

At 19 weeks 2 days my baby girl measured 17.52cm crown to rump and my friend stacy (who is due the day after me and had her scan the day before me) has a little boy measuring 15.9cm.

I think shes coming early for sure but guess its all a waiting game

I'm in the exact same situation. At 17.5 weeks I was measuring closer to 18-19 weeks and I have an ultrasound today (I'm 27 weeks I think!) and my doc is going to tell me the REAL age lol

it's confusing! I just wanna have an accurate due date
